There are two options for changing a redemption rate for a customer,
First option would be giving that customer a special rate or the other or the next option would be just for one loan.
Option 1 (Special Interest Rate)
Open the customer that you are wanting to give a special rate and select “ADMIN”
Then Select number 6. Special Interest then a popup will appear,
Then give the rate you want and click save.
Option 2 (Just for the loan)
Create a New Loan, then in the right hand corner, where it says Total Amount, Interest and Due Date,
the box next to interest like photo below,
Right Click and select Change Interest Rate, then enter your Rate and press the “TAB” Button on your keyboard.
